Malignant Pleural Mesothelioma: Clinicopathologic And Survival Characteristic In A Consecutive Series Of 40 Patients.
Published 2011 · Medicine
INTRODUCTION Pleural malignant mesothelioma is an uncommon but extremely invasive tumor which originates from mesothelial cells and usually occurs after prolonged exposure to asbestos. Different types of surgical and oncological therapeutic methods have been used resulting in various outcomes. The aim of this study was to evaluate, clinicopathologically, 40 patients with pleural malignant mesothelioma and the main factors influencing their prognosis. METHODS In this study, 40 patients with a definitive diagnosis, who had been followed up for at least 3 years were studied according to these: epidemiologic factors, stage and pathological types, treatment method and complications, and by using factors that influence patients survival, we evaluated them statistically. RESULTS The M/F ratio was l3/1 with an average age of 55 years. Chest pain was the most common symptom. In 55% of patients, the lesions were localized in the left site and most were in Buchart stage I or II. The epithelial form was the most common pathological pattern (62.5%). 47.5% of patients only received radiotherapy and chemotherapy. Of patients who underwent decortication and pleurectomy with adjuvant therapy, extrapleural was performed in 20% of patients, and pneumonectomy, in 17.5%; and 15% refused any type of treatment. One patient died from the surgery. The most common surgical complication was wound infection. The average survival was 10.5 months, and the main factors influencing the survival were physiologic status, pathological form of disease, stage of disease and the pattern of pleural involvement. CONCLUSION Because of the low survival after multimodality invasive treatments in mesothelioma, aggressive therapeutic methods were recommended in patients with good physiological status and early clinical stage with a good pathology type.
